Multiplying and working with brackets
Remember the basic rules
Place numbers before letters
Keep letters in alphabetical order
Two negatives multiply to make a positive
A negative and a positive multiply to make a negative
If an even number of negatives is multiplied, the answer is a positive (because they pair off)
If an odd number of negatives is multiplied, the answer is a negative (one is left after they pair off)
You can rearrange terms that are all being multiplied
(3 x 4 x 5 = 5 x 3 x 4 = 4 x 5 x 3; ab = ba etc…)
